Title
(EN) LIQUID END ASSEMBLY FOR A MULTICHANNEL AIR DISPLACEMENT PIPETTE
(FR) ENSEMBLE CÔTÉ LIQUIDE POUR PIPETTE À DÉPLACEMENT D'AIR MULTICANAL
Abstract
(EN) A handheld multichannel air displacement pipette is modular in construction and includes compliant joints and molded plastic components in place of various machined metal, glass, and ceramic components found in traditional multichannel pipettes. These improvements are made without sacrificing performance in channel-to-channel consistency, accuracy, and precision. The multichannel pipette is inexpensive to manufacture, lightweight, reliable, and easy to assemble and service.
(FR) La présente invention concerne une pipette à déplacement d'air multicanal manuelle, de construction modulaire et comprenant des joints souples et des composants en plastique moulé à la place de différents composants en métal usiné, en verre et en céramique que l'on trouve dans des pipettes multicanal classiques. Ces améliorations sont obtenues sans sacrifier les performances relatives à la cohérence, l'exactitude et la précision canal-à-canal. La pipette multicanal est peu onéreuse à fabriquer, légère, fiable et facile à assembler et à entretenir.
